How Many Grams are in 1 Cup of Butter?

Precision is the quiet foundation of every perfect pastry. If you are standing in your kitchen right now, wondering how many grams are in 1 cup of butter, the short answer is 227 grams. but, if you want your biscuits to rise and your crusts to shatter into flaky shards, that single number is only the beginning of the story. At ConvertThis, we believe that understanding the ‘why’ behind the weight is what separates a cook from a baker.

KEY TAKEAWAYS

One standard U.S. cup of butter equals 227 grams or 8 ounces.
Two sticks of butter (U.S.) constitute exactly one cup.
Volume measurements for solid fats are notoriously unreliable air pockets and temperature variance.
For professional results, always use a digital scale set to grams for dry and fat-based ingredients.

The Mathematical Constant of Butter Weight

In the United States, butter is sold in standardized sticks. One stick of butter is half a cup, which weighs 113.5 grams. When a recipe calls for a full cup, you are simply doubling that to 227 grams. This seems straightforward, but the complications arise the moment you pick up a measuring cup instead of a scale. Imagine two bakers. Baker A packs cold, cubed butter into a measuring cup. Baker B melts their butter and pours it in. both ‘measuring’ one cup, Baker A might actually have 210 grams of butter the air gaps between the cubes, while Baker B has exactly 227 grams. In a delicate cake batter, that 17-gram discrepancy is enough to cause the crumb to collapse or the edges to become greasy. This is why we insist on the scale.

PRO TIP: The Displacement Method

If you do not have a scale, use the water displacement method. Fill a 2-cup measuring cup with 1 cup of water. Add butter until the water level reaches the 2-cup line. You now have exactly 1 cup of submerged butter, though it will be wet and potentially difficult to incorporate depending on the recipe requirements.

Global Variations: The Metric Cup vs. The U.S. Cup

If you are following a recipe from an Australian or British blog, your ‘cup’ is not the same as a U.S. cup. Most of the world uses a ‘Metric Cup,’ which is defined as 250 milliliters. , the U.S. Legal Cup is 240 milliliters. While a 10ml difference sounds trivial, it scales.

U.S. Standard

U.S. Cup: 227 grams of butter, based on a 240ml volume container.

Metric Standard

Metric Cup: 250 grams of butter, based on a 250ml volume container. When you are converting a recipe across borders, you are not just converting units; you are converting the very vessel used to define the ratio. This is the primary reason why high-end bakeries standardize everything into grams. Grams are a universal constant. A gram of butter in New York is a gram of butter in Tokyo.

Temperature and Density: Why It Matters

Butter changes density based on its temperature. While the mass (the weight) remains the same, the volume it occupies can shift slightly. More , the way butter interacts with air during the ‘creaming’ process depends on its physical state.

The Baker’s FAQ

Can I use a 250g block of European butter for a 1-cup recipe?
Yes, but you must trim it. A standard U.S. cup is 227g. If you use the full 250g block, your recipe will be too fat-heavy, which can lead to spreading in cookies or a ‘fried’ texture in cakes. Is salted butter heavier than unsalted?
The weight remains effectively the same for culinary purposes. The salt content in a cup of butter is usually less than 2 grams, which is within the margin of error for most consumer scales. Should I weigh butter before or after melting?
Always weigh it before melting. While 227g of solid butter weighs exactly the same as 227g of melted butter, you often lose a small percentage of weight through evaporation or ‘bowl-cling’ if you weigh it after the process.
